IMPROVEMENT IN BABY-JUMPERS.`

Specication forming part of Letters Patent No. 159,639, dated February9,1875; application tiled November 21, 1874.

To all whom it may concern:

Be it known that I, DAVID FRANCIS BUE- GESS, of Lockport, in the countyof Niagara and State of New York, have made certain Improvements inBaby-Jumpers, of which the following is a specilication:

This invention relates to jumpers in which the child is held in a chairhung on springs; and my invention consists in providing a selfsupportingand portable device, the upright frame-work attached to a base, and thetop formed into a spiral spring and arm, from which the chair issuspended, as hereinafter fully explained.

1n the drawing, the figure is a general perspective view.

A represents the base orr platform, set on casters to move it about. Itis preferably of wood, and constructed either in a semicircular form, orany open segment of a circle, or made entirely circular, as representedby dotted lines in the drawing. When made circular the childs feet willtouch on the base or solid platform, and if made segmental, as shown atA', the feet of the child will reach the iioor, which will aid the childin learning` to walk. At the back of this base or circle A are attachedor hinged, at a c, two stout wires, B B, which, after rising a certaindistance, are formed at the top into a coiled or spiral spring, b, theends projecting out at about right angles, and forming an arm, c, towhich is attached or hung the childs chair G, with the usualintermediate spring d, if more elasticity is desired. To give strengthto these uprights B B, and sustain them in place, I provide two sideWires or braces, B B, their lower ends set into the base A, and at theapex arranged so as to support and sustain the spiral spring b, bypassing through it, or otherwise. The chair C is preferably constructedof wire, and has a central projection, e, to come between the childslimbs to support them either in sitting or in attempting to walk.

lhis whole construction makes my device a combined jumper, swing, andwalking-ma chine, for by the aid of the base Al and casters any motionof the childs feet on the floor will be likely to push or propel itforward or backward.

The whole device is also portable, as by hinging or looping the backframe-wires B B, and making the side braces B B removable, the wholething can be folded up and compactly set away, taking up but littleroom.

Instead of two back wires, B, it may be constructed ofa single uprighton the back 5 or the uprights may be made of wood, with the spring b andarm o connected therewith.

The advantages of my device over those I am acquainted with are that itis a self-supporting, movable, and portable baby-jum per.

By being constructed of wire it is also very light, yet strong, and canbe made comparatively cheap.

I claim- 1. The baby-jumper consisting of the movable base A, supports BB, with spring b and arm c, side braces B B', and suspended chair C, allconstructed and arranged substantially as hereinbefore specified.

2. In combination with the suspended ch air O, the supports B B, formedvat the top into the spring b and arm c, and hinged or otherwiseattached to the platform or segmental base A, as hereinbefore specified.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

DAVID FRANCIS BURGESS.
